Andrew D. Miall, in The Sedimentary Basins of the United States and Canada (Second Edition), Lower to Upper Devonian (Kaskaskia-i Sequence) By Early Devonian time, a clear distinction can be made in the Great Basin between continental margin strata, deposited on the shelf or slope of Laurentia, and arc-related rocks of the approaching Antler arc (Poole et al., . The Duvernay Formation was deposited in the Alberta Basin (part of the larger Western Canadian Sedimentary Basin) during the Late Devonian (Fig. 1, Fig. 2).During this time, global sea level was significantly higher than at present day (Johnson et al., ; Savoy and Mountjoy, ; Haq and Schutter, ), resulting in widespread flooding of continental margins and development Cited by: 1. Chapter 2 deals with both the large-scale plate tectonic history of Cordilleran development and the smaller-scale deformational history of the Rocky Mountain Thrust and Fold Belt. Balanced and restored structural cross sections through the Rockies are . Beneath the Cretaceous oil sand deposits in Alberta, Canada, Upper Devonian carbonates form the Grosmont reservoir in a huge carbonate platform or ramp that hosts at least billion barrels of “Initial Oil In Place” (IOIP) in the form of low-gravity (American Petroleum Institute gravity = API gravity of ~5° to ~9°) bitumen (Hein et al. , Wo et al. ), by some estimates up to.

The Upper Devonian Big Valley Formation in southern Alberta is a m thick carbonate succession, unconformably overlain by organic-rich source rocks of the Exshaw Formation. The Exshaw Formation is part of a global continuum of mudrocks deposited under anoxic conditions, representing a distinct interval in Earth’s climatic, terrestrial and marine evolution, and the Author: Jacqueline Colborne. Regional sequence stratigraphic interpretation of the Alberta Devonian has been limited (Wong et al. a, Potma et al. ). Imperial Oil geologists illustrated the transgressive–regressive nature of the Devonian Alberta Basin (figure of McCrossan modified by Maiklem et al. ).   Figure The distribution of Mesozoic sedimentary rocks in the Western Canada Sedimentary Basin.

[SE after Alberta Geological Survey] From time to time during the Mesozoic, the WCSB was filled to varying degrees with marine : Steven Earle.   The Acadian orogeny occurred near the beginning of a major period of mountain building in earth's history lasting for million years. Nearly every continent was affected. A t the same time, sea level was rising and the Kaskaskia Sea, entering from the Gulf of Mexico, spread north across North America, placing most of it under water. Eventually it lapped onto the inland .

In northern Alberta, a sea-level lowstand resulted in an incised valley system several hundred kilometres long, cut into the Middle Albian Cadotte Member, from the Rocky Mountain Foothills to the Interior Plains. This incised valley system is coeval with multiple paleosols in the Boulder Creek Formation in northern British Columbia (Leckie et.   Jasper National Park comprises all of the land drained by Athabasca River and its tributaries above the western end of Brûlé Lake, in addition to a large area drained by Brazeau River in the southeastern corner and a smaller area drained by Smoky River in the extreme northwestern corner. The park lies wholly within the Province of Alberta. The North American Stratigraphic Code seeks to describe explicit practices for classifying and naming all formally defined geologic units. Stratigraphic procedures and principles, although developed initially to bring order to strata and the events recorded therein, are applicable to all earth materials, not solely to strata.
